Transient lunar phenomena
Transient Lunar Phenomena by definition is any change in brightness on the surface of the moon. These changes come in many forms and are attributed to releasing of gas or volcanic matter from under the moon's crust. The existence of transient lunar phenomena argues against an origin of billions of years ago.
The Moon has long been presumed to be virtually "dead". It has surface features that have been preserved from a time long, long ago. But the moon is not unchanged. Many changes on the surface of the moon have been observed. A large amount of these changes are found around certain location, including the Aristarchus and Alphonsus craters. This, along with bright spots, streaks of light, mists and colored glows point toward the conclusion that there are event of volcanic activity occurring on the moon. This contradicts the idea that the moon, is cold, lacking heat within its core, and geologically inactive. These occurrences of TLP (Transient Lunar Phenomena) are not meteorite strikes, even though the definition of a TLP is being changed to include meteorite strikes. 
Since telescopes were invented, people have been sighting events of TLP. According to NASA, there have been 579 reported incidents since the 1600s. These events are relatively small and last only a few hours. People have been unable to study them thoroughly because they have probably ended by the time they are reported. Astronomers can only go by secondhand observations when compiling the facts. No one has any physical proof of what TLPs truly are, but all the known information suggests that they must be some form of volcanic discharge. Some sightings of TLPs have been recorded by astronomers William Herschel, in 1783-1787, and Audouin Dollfus (of France), in 1992. Herschel wrote "I perceived in the dark part of the moon a luminous spot. It had the appearance of a red star." and later "I perceive three volcanoes... The third shows signs of an actual eruption of fire, or luminous matter." Dollfus wrote of having seen "diffuse brightening near the center of the lunar crater Langrenus. The haze resembles a gas cloud which was emitted from the craters central peak."There are multiple "hot spots" where transient phenomena is often sighted. The crater, Aristarchus is the most frequent of these. Since the 6th century, people have been reporting brief transient phenomena at this crater. This graph shows a 29 day period, in which the reports of transient phenomena were recorded. There was no specific pattern; the amount of events varied greatly with each day. 
A popular theory for the origin of the moon is the collision theory, that two planetesimals were moving through the solar system and collide. This theory, says that the earth and moon formed at the same time from the same matter that was ejected from the collision. Then the pre-moon was bombarded by smaller planetesimals that orbiting the sun in the early solar system. Then the gravitational pull of the object brought all of the pieces together to form the moon. There are other problems with this theory then just the existence of TLPs. It's improbable that the pull of gravity from the matter would have been strong enough. 
Then radioactive decay melted the moon's outside and inside, and after billions of years all the heat disapated. Creationists believe the moon was created by God on the fourth day of creation as written in the account in Genesis 1. The idea of a young moon does not conflict with TLPs as an ancient moon would. by Don DeYoung, TJ volume 17(1) 2003
With the idea that the moon is billions of years old, than the interior of the moon would no longer have any significant heat. It would have all dissapated a long time ago. The moon is thought to have a very small molten core about 1500 kilometers below the surface, but it is too far down to cause any activity on the surface. But these TLPs are signs of this activity and show that the molten core of the moon may much bigger and closer to the surface. TLPs are dimissed as being tricks of the eyes or mistakes resulting from poor observation because there is no physical proof of what they really are. The most logical explanation is that they are forms of volcanic activity and this idea would be widely excepted by secular scientists if only they didn't have to hold to the belief that the moon was ancient and couldn't be geologically active anymore. They come up with other explanations such moonquakes or high-energy cosmic rays hitting the moon.
